All xills are female, and they fertilize their own eggs, but they require a host body to incubate their eggs before they hatch. For this reason, they use their poisoned mandibles to paralyze their victims and implant eggs in their bodies with an ovipositor usually kept retracted behind their jaws. Xills particularly favor phase spiders as incubators.
Habitat and society
Xills inhabit the gray mists of the Ethereal Plane. They are highly intelligent, with a repressive, militaristic culture. Due to their need to reproduce, they are driven toward conquest, constantly seeking new incubators for their eggs. Xills often find themselves in conflict with the more powerful night hags, and are in a state of eternal war with the phase spiders, their favored source of incubators. Xills and destrachans are mortal enemies.
A strange subspecies of chaotic, green-scaled xills inhabits the ruins of Valashai in the Valashmai Jungle. These xills, native to the Material Plane, take slaves to use as incubators. They prize arcane magic, and tribes are led by sorcerers or summoners with ties to the Abyss.
